The Road to Cloud Native VNFs

Many of the existing network functions, such as routers, firewalls, load balancers and such, haves gone through the first transition from a physical appliance to a virtual appliance. Where that transition required mostly performance optimization to accommodate the additional I/O overhead of the hypervisor and some configuration changes to accommodate the fact that a VM can be more dynamic in nature.

This transition to NFV, which is basically a cloud based data center, has revolutionized the way network functions can be delivered. The transition to a Cloud Native world is considered far more disruptive as it touches changes in both the architecture (to accommodate hyper-scale and multi-tenancy) as well as a business model that needs to be more consumption based, rather than fixed.

This talk will dive into the main requirements that differentiate a cloud native network function from the traditional network function, as well as what is required to achieve cloud-native capabilities, along with the challenges and benefits of this transition.

Nati will discuss the primary characteristics that are expected from a Cloud Native VNF:

- Self-Management

- Multi-Tenancy

- Being Software Defined

He will also show how open source cloud orchestration tools can make this transition seamless and ensure full lifecycle management of your VNF.

Other Considerations
● Multi Tenancy
○ Share the same VNF between multiple
users
○ Have separate VNF per (IaaS) tenant
● Multi Cloud (VIM) Support
○ Operators have different cloud flavour and
preferences
○ Be ready to support the common platform
to maximize your market reach

Cloudify Embeddable Orchestration
VNF providers should consider ARIA to gain TOSCA support,
automation of deployment and configuration across multiple
clouds such as OpenStack, VMware, (or any other cloud), as
well as portability between different container-based
architectures such as Docker Swarm or Kubernetes.
Cloudify includes ARIA as its orchestration engine, so by
definition, it inherits all of its capabilities in addition to the
capabilities that are provided by Cloudify Manager.
VNF providers should consider Cloudify in cases where they
would want to gain more advanced management, ongoing
automation and security such as:
- Self-healing
- Auto-scaling
- Monitoring
- Policy Management
- Security and Multi-Tenancy
